SLUB GATCHER OR YARN: CLEANER.

Application filed Maia 19, 1927. Serial Nanette.

This invention] relates to improvements in'slub-catchers oryarn-cleaners for removing slubs, bunches, motes or other foreign matterfrom thread or yarn'during the process of winding or otherwisetransferring the material. 4

One object of the invention is to provide a device of the type specifiedhaving-a slot .or opening through which'the yarn draws with means forsec'uring'a precise, accuratev adjustment'inthe width of the slot inaccordance with different sizes or thicknesses of yarnto be operatedupon. v I Another objectof the invention is to provide an adjustingmeans for the slub-catcher which is operative onlythrough the use of aspecial key or wrench so as to prevent unauthorized tampering with orchange in the adjustment of the device afterit has once been set. a .1 Hi c, A V Anotherobject of the invention isto provide a device of thetype specified having means for maintaining the yarn slotfor maximumefliciency in whatever position the I i an extension 7 formingza part ofthe windmgimachlne frame; The arms-or bracketjG.

In the drawings: a Fig. 1' is a side elevationof a portion of a winding machine showing my improved slub-catcher oryarn-cleaner'applied to use therewith;

In winding. machines ofthe present f y it is usual to apply tension tothe yarnor thread y as it"drawsgfromj its supplyandI feeds to thethread-guidie and the reference numeral indicates in general a'preferred 7 form oftension-device for thi'spurpose. As hereinillustrated; the'FtenSion-deVice 5 is supported on an arm Oribracket- 6bolted to ing between their opposed faces in accordancewith the usualarrangement.

r My improved 'slub-catcher or yarn cleaner as herein illustrated isadapted to be mounted' on a finger or lug 12 on the sidegof the armorbracket 6. Referring now to Figs 3 to 5, the improved device comprisesin gen eral a fixed member 1 5 constructed inthe form of a sheet-metalplate or blade and a i movable vplate or blade 16-.adaptedto: be

' mounte'd in. opposite relationtheret'otollprovide a 'slotor openingbetween {their parallel edges; Referring particularly to F ig b,thefixed vmember 15 has a foot {or support 17 bent at right-angles totheplane of its blade and provided with a hole 18 adapted to, re-

ceive-a screw,19 which attaches'it to the top i of thelug 12 onthebracketj'G I As adaptedfor use with-the tension-device herein-illustrated,the' members 15 andf16f are thefblade 15 beingproacrosswhich the yarn draws and the cooperating upper blade 16 havinga similar straight edge21 arranged in parallel spaced 'relation thereto.The main blade is arme with a re an a r g d 2 extending upwardlyfrom-its base or ,foot

17 and provided with a substantially V- shaped groove 23-011 itsrearward "face ;ex

/ tending'parallel with and adjacent its side.

The blade 16 is'constructed in the form V of a rectangular strip bent or'foldedaround at its end in the loop-portion 24 which is adapted toenclosethe upright arm or guide I 22 onthe blade 15. Tl ie 'earwardfolded orti'on ofthe loop 24 is bentinwardly at 'ItSQDdtO-PI'OVl QlQ akey or spline 26; the forward edgefqf which is adapted to; engage andslide in the groove 23 on the back of the a1'n1 22. Itwill be noted fromFigs. 4 and :57, tha-t the blade 16 is'o'f slightly thinner metal thanthe main blade 15 and its main portion offset rearwardly from the foreward part ofthe loop 24 to bring its lower operating't-edge -2 lv-into'alinenient with the edge 20' 'o-if rthe blade 15. That'is to say,

when the parts are'assembled in operative position as'shown in Figs. 3and 4 the front faces of the blades 15 and 16 standin the same verticalplane with their edges 20 and 21 in spacedfrelation to'provide :the slotor opening 27'through whichthe thread oryarn extending inclined finger28 and the outer end oflt he upper ib1ade-16 is chainfered or beveled*o'fi' at '29 to pro'vide a substantially aped mouth orentranceforiguiding the '31 1 nto thesl :21

I u The stud '33 is formed with an; enlarged head 34 provided with aholeior socketf35in its forward}endadapted "to receive a: suitablewrench or key for turn ng 'th'e stud; The socket 35 may be square on'hex agonal as shown to correspond with the shape of the key or wrenchwhich is thus'ogtspecial form so that thestud can? not be turned withthe usual type of wrench or screw-driver, 7 At the rear of the hea-d"34V the stud 33 isformed -With an eccentric "hub o-r b'ojss 36 ofathickness toadapt it to pass through andf-engage with the 's-ides'of theslot 30 in'the loo 24 Of thelblade 16.; The

of the blade 16. A washer 38 is then applied to-the stud 33 with the endotthe latter riveted thereover at 39 as shown in Fig. 4.

The riveting of the stud at its rearward v Venddrawsits head-snuglyagainst the i 01 ward part of the loop 24 on the blade 16 with theeccentric hub or boss 36 received in andengaging the sides of the slot30. The blade 16 will thus be secured firlnlyin place on the uprightarin22 of theblade 15 with its spline-or key 26 engaging'the'vertical groove28. Due to' the spring tendency of the loop 24the key 26 engages thegroove '23 with a slight friction so as to prevent play between theparts and also to providea slight resistance to the sliding movement ofWhen itis desired to adjust the width of the slot or opening 27-betweenthe 'cooperat-f' ing edges 2.0 and-2'l-of .the'blades =15'an'd16. a suitable key onwrench isxinserte'd'in the hole 35in the hea'd 34of the stud 33 to turn Rotation of lthezstud 33 will cause its eccentrichub or boss 36. to act on the sides of the slot 30 to slide theblade 16upwardly or downwardly on the arn'1'22 in accordance with the directionin' whichthe stud is turned. The eccentricity of the hub or boss '36 isrelatively slight so that the stud 33 must be turned to a considerabledegreeto adjust the blade v16 to a very slight extent. "Thatis to say,the arrangement of 1 the adjusting means is such that a'very fine 1adjustmentmay'be secured .so that the width 4 i of theslit27 can bevaried within precise limits and with great accuracy in accordancewithfithemsize io-r thiekness of the yarnatobe op'erated upon.
